From 23ce932a5e3ec3b9f06e92c8797d834d43abfb0f Mon Sep 17 00:00:00 2001 From: Rakib Mullick Date: Mon, 14 Dec 2009 17:59:44 -0800 Subject: [PATCH] mm: fix section mismatch in memory_hotplug.c __free_pages_bootmem() is a __meminit function - which has been called from put_pages_bootmem thus causes a section mismatch warning. We were warned by the following warning: LD mm/built-in.o WARNING: mm/built-in.o(.text+0x26b22): Section mismatch in reference from the function put_page_bootmem() to the function .meminit.text:__free_pages_bootmem() The function put_page_bootmem() references the function __meminit __free_pages_bootmem(). This is often because put_page_bootmem lacks a __meminit annotation or the annotation of __free_pages_bootmem is wrong.
